"From what we understand the rape stemmed from an argument between him and his brother. And apparently they were arguing over a girlfriend. And the rape was some sort of retaliation towards his brother," said Sgt. Jamie Smith of the Albertville Police Department.

Authorities say Helms' mother was apparently passed out drunk on the couch when the rape started.

"During the attack she did come to and recognize her attacker. (Reporter: As her son?) As her son," said Smith.

That's when, according to the police report, the mother "tried to get away, but he held her down until he was finished."
